Si quieres Scrapear Tweets con PHP puedes hacerlo con el siguiente código para trabajar con su API, eso si necesitas solicitar tus credenciales desde
https://dev.twitter.com/
Código de autentificación con el API de Twitter:
Código:
//Usuario de Twitter que quieres scrapear sus tweets
$twitter_handle = "usuario";
function buildBaseString($baseURI, $method, $params) {
$r = array();
ksort($params);
foreach($params as $key=>$value){
$r[] = "$key=" . rawurlencode($value);
}
return $method."&" . rawurlencode($baseURI) . '&' . rawurlencode(implode('&', $r));
}
function buildAuthorizationHeader($oauth) {
$r = 'Authorization: OAuth ';
$values = array();
foreach($oauth as $key=>$value)
$values[] = "$key=\"" . rawurlencode($value) . "\"";
$r .= implode(', ', $values);
return $r;
}
$url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
$oauth_access_token = "your own";
$oauth_access_token_secret = "your own";
$consumer_key = "your own";
$consumer_secret = "your own";
$oauth = array( 'oauth_consumer_key' => $consumer_key,
'oauth_nonce' => time(),
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_token' => $oauth_access_token,
'oauth_timestamp' => time(),
'oauth_version' => '1.0',
'screen_name' => $twitter_handle);
$base_info = buildBaseString($url, 'GET', $oauth);
$composite_key = rawurlencode($consumer_secret) . '&' . rawurlencode($oauth_access_token_secret);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;
// Make Requests
$header = array(buildAuthorizationHeader($oauth), 'Content-Type: application/json', 'Expect:');
$options = array( CURLOPT_HTTPHEADER => $header,
//CURLOPT_POSTFIELDS => $postfields,
CURLOPT_HEADER => false,
CURLOPT_URL => $url . '?screen_name=' . $twitter_handle,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false);
$feed = curl_init();
curl_setopt_array($feed, $options);
$json = curl_exec($feed);
curl_close($feed);
Código para mostrar los últimos tweets:
Código:
$decode = json_decode($json, true); //getting the file content as array
echo '<ul>';
foreach($decode as $tweet) {
$tweet_text = $tweet["text"];
echo '<li>';
echo $tweet_text;
echo '</li>';
}
echo '</ul>';
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
$reg_exHash = "/#([a-z_0-9]+)/i";
$reg_exUser = "/@([a-z_0-9]+)/i";
echo '<ul>';
foreach ($decode as $tweet) {
$tweet_text = $tweet["text"]; //get the tweet
// make links link to URL
// http://css-tricks.com/snippets/php/find-urls-in-text-make-links/
if(preg_match($reg_exUrl, $tweet_text, $url)) {
// make the urls hyper links
$tweet_text = preg_replace($reg_exUrl, "<a href='{$url[0]}'>{$url[0]}</a> ", $tweet_text);
}
if(preg_match($reg_exHash, $tweet_text, $hash)) {
// make the hash tags hyper links https://twitter.com/search?q=%23truth
$tweet_text = preg_replace($reg_exHash, "<a href='https://twitter.com/search?q={$hash[0]}'>{$hash[0]}</a> ", $tweet_text);
// swap out the # in the URL to make %23
$tweet_text = str_replace("/search?q=#", "/search?q=%23", $tweet_text );
}
if(preg_match($reg_exUser, $tweet_text, $user)) {
$tweet_text = preg_replace("/@([a-z_0-9]+)/i", "<a href='http://twitter.com/$1'>$0</a>", $tweet_text);
}
// display each tweet in a list item
echo "<li>" . $tweet_text . "</li>";
}
echo '</ul>';
Este código PHP lo he sacado de (trabaja con la versión actual del API de Twitter v1.1):
